Our silica gel consists of silicon dioxide that is purified, and it has an average pore size of 2.4 nanometers and a strong affinity for water molecules
It performs best at room temperature and drops a relative humidity of RH 60% to RH 90% in a container to around RH 40%, and it has been approved by the FDA
